It was he who suggested transferring the active ingredient of penicillin back into water by changing its acidity, thus purifying the penicillin.

Heatley recorded these trials, carried out on eight mice in May , in his diary:. On returning home, he realised that in haste and darkness, he had put his underpants on back to front, and noted this in his diary too, adding "It really looks as if penicillin may be of practical importance. These were in short supply because the ongoing World War II , so Heatley designed a modified version which was manufactured in the Potteries.

With the help of these, the Oxford laboratory became the first penicillin factory, and subsequent tests on humans proved the efficacy of the new treatment. Even so, it was very difficult to produce enough for sustained treatment. In December , a year-old police constable, Albert Alexander , was accidentally scratched by a rose thorn on his mouth, and was succumbing to septicaemia. Alexander was admitted to the Radcliffe Infirmary , where various conventional treatments all failed, and his case was brought to Florey and Heatley's attention. A patient in a terminal condition with nothing to lose was needed as a human volunteer, and Constable Alexander met this requirement. On 12 February , Alexander was given an intravenous infusion of mg units of penicillin.

Within 24 hours, Alexander's temperature had dropped, his appetite had returned and the infection had begun to subside. However, owing to the instability of penicillin and the wartime restrictions placed on Florey's laboratory, only a small quantity was available, and although Florey and colleagues extracted any remaining penicillin from Alexander's urine, they had run out by the fifth day and Alexander died a month later. Eventually Heatley and Florey travelled to the United States in because they wanted to produce about one kilogram of pure penicillin, and persuaded a laboratory in Peoria, Illinois , to develop larger-scale manufacturing of it.

In Peoria, Heatley was assigned to work with Dr. Moyer suggested adding corn-steep liquor, a by-product of starch extraction, to the growth medium. With this and other subtle changes, such as using lactose in place of glucose, they were able to push up yields of penicillin to 20 units per milliliter. But their cooperation had become one-sided. Heatley noted, "Moyer had begun not telling me what he was doing. In July he returned to Oxford, and was soon to learn why Moyer had become so secretive.

When he published their research results, he omitted Heatley's name from the paper, despite an original contract which stipulated that any publications should be jointly authored.
